摘要: Studies of populations in fragmented habitats have become essential tools biodiversity conservation. This study was conducted at 14 natural forest patches (“capoes”) the Serra da Canastra National Park, with purpose evaluating bird species richness these relation to patch area and distance other patches. In this study, isolation did not explain much variation abundance when all were considered. However, only forest-dependent considered, both significantly related richness, suggesting that distribution birds is highly limited by dispersal ability through matrix. But, some individuals (Thamnophilus caerulescens, Basileuterus leucophrys) also found very small (0.05 ha) or most isolated (430 700 m) fact may be an adaptation naturally landscape, since a landscape which been altered considerably last two centuries. Our results showed imbedded grassland matrix support several birds, increasing regional biodiversity.
